DisplayMate is out today with a comparison of iPad displays following the introduction of Apple’s new larger 12.9-inch iPad, and the results might surprise you.

While the larger display on the iPad Pro is one of the device’s standout features on Apple’s latest and greatest iPad, the iPad mini 4, introduced alongside the iPad Pro to not quite as much fanfare, actually beats out its bigger sibling in several categories. The iPad Pro, however, does hold its own and DisplayMate’s analysis shows a number of improvements Apple has made to make it one of its best displays for a mobile device yet.

DisplayMate also spotted a new “Metal Oxide TFT Backplane” and “a lower refresh rate when the images remain static,” both of which make the display Apple’s most power efficient of all its iPad models. DisplayMate also adds that the “Display Power Efficiencies for the iPad mini 4 and iPad Pro are 22% to 33% higher than the iPad Air 2.”

And while the iPad Pro beat out Apple’s last full size iPad, the iPad Air 2, with “Very Good” or “Excellent” scores for each of the categories DisplayMate tested (including the highest true contrast ratios of any tablet LCD yet), the iPad mini 4’s display did beat out the iPad Pro in a few areas making it still Apple’s best tablet display overall for its iPad lineup.

Areas the iPad mini 4 beat iPad Pro include Color Gamut, which the report notes is not as good on iPad Pro due to “over saturated Blue primaries, which reduces their Color Accuracy.”

The iPad mini 4 also won for Absolute Color Accuracy and low screen reflectance.

And lastly, the report sheds some light on how the iPad Pro display performs versus Microsoft’s Surface Pro 4, noting that the iPad has “much lower Screen Reflectance (2.6 versus 5.6 percent)” and that the Surface has “much better Absolute Color Accuracy”.
